| 摘 要： | 采用胸鳍覆盖处的体表鳞片为研究勒笛绸年龄的鉴定材料，判断年轮的依据是以环片切割现象为主，结合环片排列的疏密现象。鳞径（Ｒ）与体长（Ｌ）的关系为Ｌ＝１９．８１５９＋６３．３６９６Ｒ。用ＶｏｎＢｅｒｔａｌａｎｆｆｙ生长方程可表达体长、体重与年龄的关系为Ｌ＝４６９．８［１－ｅ－０．２４２５（ｔ＋０．３７６２）］、Ｗｔ＝３３６６．６［１－ｅ－０．２４２ ５（ｔ＋０．３７６ ２）］３，生长拐点ｔｒ＝４．１５ａ。作为渔业管理对策，勒氏笛鲷捕捞年龄应定在４龄以上，人工养殖年限以２～３龄最好。

| Abstract: | The scale under pectoral fin is selected for the age determination material of Lutjanusrusselli in the littoral waters of Zhanjiang. The relationship between the length of the scale (R,mm) and the body length (L, mm) is expressed as L=19.815 9 63. 96R(r=0. 991 6). The relationship between body length or body weight (W, g) and age can be described by the VonBertalanffy growth equation:Lt= 46.8[1-e-0. 242 5(t 0. 376 2)]; WtM=3 366. 6[1-e-0. 242 5(t 0. 376 2)]3;growth inflection tr=4. 55a. As a strategy of fishery management. the harvesting age can be decided above four years of age.Under the condition of artificial raise, the cycle of cultivation canbe determined at two to three years of age. |
